我想通过基本示例以更综合的方式提出我的问题。

1) I have UsersController
2) I have show method in it
3) But I don't have any templates for this method(either - show.html.erb/show.xml.erb etc)
4) So currently, I just wanted to write a spec for just checking whether my method is returning an object or not
5) it is working, but as it is CRUD related method, it is expecting a Template for it.
6) ActionView::MissingTemplate

我试过这种方式

it "should show the user record" do
  get :show, :id => 1
  User.should_receive(:find).at_least(:once).with(1).and_return(mock_user)
end

class UsersController
  def show
    # params = {}
    # params = {:id => 1}
    @user_obj = User.find(params[:id]) # ActiveRecord::Relation
  end
end

require 'spec_helper'

describe UsersController do
  def mock_user(stubs={})
    @mock_user ||= mock_model(User, stubs).as_null_object
  end

  it "should show the user record" do
    expect(assigns(:user_obj)).to eq(mock_user) # How to stop execution  here only.
  end
end

ActionView::MissingTemplate: 缺少模板用户/显示 {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html], :locale=>[:en, :en]} 在视图路径“#”中

您缺少渲染，因此它会搜索要渲染的模板。

class UsersController
  def show
    # params = {}
    # params = {:id => 1}
    @user_obj = User.find(params[:id])
    render status: 200, json: @user_obj
  end
end

现在你的规格应该工作。

你试图做的事情似乎不适合我。这种类型的测试（控制器测试是）用于测试动作和渲染的响应。所以你不应该这样做，你应该测试动作渲染的输出。否则，如果您只想测试该方法 show（单元测试），请不要get在此处使用，您可以这样做

users_controller = UsersController.new
users_controller.show

并将其作为任何类中的任何方法进行测试
